Roof Replacement in Pflugerville, Texas

Pflugerville roofs tend to arrive at a replacement decision for reasons that have nothing to do with the shingles. The ground is deep Blackland Prairie clay that swells through wet stretches and shrinks through dry ones, and that movement travels up through the slab and the frame until it reaches the roof, where it works on every place two things have to stay sealed to one another.

A replacement stops none of that. What it can do is put an assembly up there that handles it better than the one coming off. That is a specification question rather than a product question, and it is worth being specific about what changes.

The layer nobody sees is the one that earns its keep here

Underlayment is the second line of defense, and on ground that moves it is the line that matters. When a joint opens by a fraction of an inch, whatever was rolled out before the shingles went on is the only thing standing between that opening and the deck.

Two decisions belong in the document. The first is the field underlayment itself. Synthetic sheet has largely displaced felt for reasons that show up in exactly these conditions: it holds fasteners better, it does not wrinkle when it takes rain during construction, and it survives a longer dry-in if the schedule slips.

The second, and the more important one here, is where self-adhered membrane goes. Self-adhered membrane seals around a fastener rather than simply being punctured by it, which is the property that counts at a joint being worked open and closed by the ground. It belongs at the locations that actually move: valleys, the full run of every roof-to-wall junction, around chimneys, and around penetrations.

That is not a general upgrade applied everywhere for its own sake. It is a targeted response to a particular soil. A roof on stable ground can perform for decades without it. A roof on clay that cycles will open joints, and the only question is whether anything is underneath them when it does.

Flashing gets replaced, not carried forward

The largest single weakness in a replacement scope on this ground is reused metal. A reroof that puts new shingles around the existing chimney flashing has renewed the part of the roof that was not the problem.

Every piece of step flashing comes off and goes back new, tucked behind the wall covering rather than sealed to the face of it. Every pipe boot gets replaced. Valley metal gets replaced. And at chimneys and masonry walls, the detail worth specifying is a two-piece assembly: base flashing tied into the roofing, counterflashing separate and mechanically held, so that when the structure moves again the counterflashing can be released and reset without taking the roof apart around it.

That is the difference between a detail built for a stable house and a detail built for this one. Sealant has a service life and clay does not respect it. A roof here is better off with joints that can be maintained than with joints that were sealed once and declared finished.

Bringing the attic up to current practice

The town filled in through the 1990s and 2000s on ground that had been farmland, and a good deal of that stock was ventilated to the minimum arrangement of its day and never revisited. Exhaust has been added over the years on some houses, which is not the same thing as ventilating an attic. Exhaust with no matching intake does not move air through the space, it draws conditioned air up out of the house.

A tear-off is the one occasion when the whole system is reachable at once. Intake at the eaves is accessible from outside with the covering off, so soffit intake that has been packed shut with insulation can actually be cleared rather than noted. Exhaust can be specified as one coherent type instead of an accumulation of whatever was added when. And the two can be sized against each other as a balanced pair, which is the part that decides whether any of it works.

So the scope should describe ventilation as a system with intake and exhaust stated together. A count of vents on a page describes nothing at all.

The 2023 replacements that are only happening now

The 24 September 2023 hail event covered Pflugerville. It is still the costliest hail night on record here, and the metro-wide damage figure attached to it is roughly $600 million. It came down after dark, nothing looked different in the morning, and a great many roofs were never examined at all.

Hail of consequence breaks the fiberglass mat under the granules without producing a leak at the time, which is why some of the replacements happening now are for a night nearly three years back. On those jobs it is worth documenting the roof before it comes off, because the tear-off destroys the only physical evidence of what the storm did.

Putting the joint work in writing

A scope written for this ground should read as a list of joints rather than as a description of a shingle. Every wall junction, every valley, every chimney, and every penetration named individually, with the material and method for each, and each one identified as new rather than reused.

It should also be honest about its limits. A structure that has moved will keep moving, and the flashing at one wall may need attention again in a few years. Saying so at the outset, and specifying details that can be serviced when the time comes, produces a better outcome than a document implying that a roof is a permanent answer to a soil problem.

The workmanship warranty covers the installation and is a separate document from the manufacturer’s material warranty on the products. On this ground it is worth having both in hand and knowing which one speaks to what, because the failures that show up here are almost always about how a joint was built rather than about what it was built from.
